same time that Linne's Boa orophias was the same species as that named Con- 

 strictor diviniloquus by Laurenti (1768). The latter name, variously spelled, 

 has usually been used for the Lesser Antillean Constrictor. Boulenger had, in 

 1893, specimens in the British museum from St. Lucia, Dominica, and' Trinidad. 

 The Philadelphia Zoological garden has had one said to have been taken upon 

 St. Kitts. 



Andersson (Bihang K. Svensk. vet.-akad. Handl., 1899, 24, afd. 4, no. 6, 

 p. 33) also shows that the type of Linne's Boa orophias is the same as the later 

 named divirdloqua.

This species is the Cuban representative of a small genus, the other two 

 species of which occur in Central America. It is a strictly aquatic snake which 

 never leaves the water. It is not uncommon about ponds and rivers, both 

 rushing and sluggish. It does not often sun itself, but remains for the most 

 part liidden in dense aquatic vegetation or among and under loose stones. The 

 natives all say that it is nocturnal and that they often meet it in rivers swimming 

 about when they are fording the streams by night. It is a difficult species to 

 find, but is undoubtedly rather common and widespread. I have specimens 

 from near Cienfuegos and San Diego de los Banos while I saw others near Pinar 

 del Rio city, and near Herradura. It is called "catibo," and I often heard of it 

 by this name in other parts of the island. In 1913 I caught it in the Rio Tana, 

 Ingenio "San Ramon," not far from Manzanillo.

Recorded by Boulenger from St. Vincent. A species common and wide- 

 spread on the mainland (Proc. Zool. soc. London, 1891, p. 355). In the Cata- 

 logue {loc. cit.) Boulenger mentions a specimen from Grenada sent by this 

 Museum to the British museum. Garman collected examples only on St. Vincent, 

 to judge by his paper on West Indian snakes (Proc. Amer. philos. soc, 1887, 

 24, p. 284). I can find no Grenadian examples in the Museum now, and Garman 

 would not have been likely to have sent the only one from tliis locality to London. 

 Neither Dr. Allen nor Mr. Brues, in their recent exploration of Grenada, saw or 

 heard of this species, so that in all probabiUty the British museum's snake came 

 from Kingston, St. Vincent, apparently the only island where Garman found the
